Warcraft 3, Halo on New iMac??

Hi,
Just a quick question before I (probably) 'take the plunge' -can the new iMacs (Radeon9600s) run WC3 at full settings in 4v4 online matches? How about Halo at medium settings (and with a good framerate,)?? I don't intend to game too much, but these are two games I enjoy playing on my PC (R9700 pro) and would like to play at full detail on Mac, yet could not on my ibook or former PM(R7500)...?? Also does anyone have a link to Doom3 benchmarks on the new imacs? [not that I need to play that too, lol ]
